The term “transnational organised crime” (TOC) has been used to describe different realities, depending on the specific category of crime and region of the world concerned. As part of the Springer book series Advanced Sciences and Technologies for Security Applications, this edited book entitled Transnational Unconventional Organized Crime: Volume II: Regional and National Perspectives seeks to explore and understand the complexity of TOC and unconventional crime in various regional and national incarnations. Globalisation has been identified as an essential factor facilitating transnational crime by removing previously established boundaries. This complicated process of globalisation has led to similar interdependencies amongst countries and cultures with various long-term and multifaceted impacts. This interconnected framework has allowed transnational criminal networks to emerge and adapt, leading to distinctly regional impacts, as the various chapters in this book will show. The editors hope that this volume will promote a better understanding of the challenges inherent to tackling TOC, which, in turn, can helpfully inform responsible and flexible responses that are tailored to the specific conditions in various regions and countries.
